Outline of Research at the Start

Lignin, a major component of woody biomass, is an aromatic polymer. Depolymerization of Lignin often gives a lot of underutilized dimers. This research aims to convert these dimers into valuable poly-aromatic hydrocarbon chemicals. As a result, more aromatic units in lignin could be utilized.
